In US gluten-free products must now meet Food and Drug Administration rules. In August 2013 the Fda issued a final rule in the Federal Register defining what characteristics a food must have to be labeled “gluten-free”. A year later, that rule is in effect, and any food product bearing a gluten-free claim labeled on or after August 4, 2014, must meet the rule’s requirements.
In order to use the term on its label, a food must meet all of the requirements of the definition, including that the food must contain less than 20 parts per million of gluten, according to the Fda. The rule also requires foods with the claims “no gluten,” “free of gluten” and “without gluten” to meet the definition for “gluten-free”.
The Fda has indicated that any food packaging that fails to meet the requirements «will be subject to regulatory action».
